  • Patent number: 11163073
    Abstract: Among other things, one or more techniques and/or systems are described for creating virtual channels in an imaging modality. The imaging modality comprises a plurality of charge integrating channels. Information yielded from two or more charge integrating channels during a same or similar acquisition view may be combined to yield a virtual channel that represents a portion of the detection surface substantially equivalent to an area comprised by the two or more charge integrating channels. In one embodiment, within a same acquisition view, some virtual channels may comprise a different number of charge integrating channels than other virtual channels. Also, different sets of virtual channels may be created for a same acquisition view to produce different images from a single set of data, for example, where there may be overlap between virtual channels such that the same charge integrating channel is comprised in more than one virtual channel.

  • Patent number: 10206649
    Abstract: A receiving antenna for wirelessly receiving data between a stator of a computed tomography (CT) imaging modality and a rotor of the CT imaging modality is provided. The rotor rotates about a rotational axis. The receiving antenna includes a dielectric portion and a conductive portion coupled to the dielectric portion. A second surface of the conductive portion extends between a first end and a second end along a conductive axis that is substantially perpendicular to the rotational axis. The second surface of the conductive portion has a first length at a first length location along a first length axis that is substantially parallel to the conductive axis. The second surface of the conductive portion has a second length at a second length location along a second length axis that is substantially parallel to the conductive axis. The first length is different than the second length.

  • Patent number: 9853694
    Abstract: Among other things, one or more techniques and/or systems are described herein for transferring communication information between a stationary unit and a movable (e.g., rotating) unit, or between two movable units without contact between the units. A transmitter is configured to translate digital information into an analog signal which may be fed to an input coupler positioned within a channel of an electrically conductive member (e.g., on a first unit, such as a stationary unit). The current of the signal induces a signal in an output coupler (e.g., on a second unit, such as a movable unit). Voltage characteristics of the induced signal (e.g., which substantially correspond to voltage characteristics of the signal fed into the input coupler) may subsequently be used to reconstruct the digital data at a receiver. In this manner, information can be communicated between two non-contacting units.

  • Patent number: 9588239
    Abstract: Among other things, one or more techniques and/or systems are described for generating an output of a detector cell of a photon counting detector array. A counter block generates integration data and photon counting data associated with the photon counting detector array. Responsive to a number of detection events counted during a measurement interval (e.g., a view) not exceeding a first detection event count threshold, a first output may be generated based upon the photon counting data. Responsive to the number of detection events exceeding a second detection event count threshold, a second output may be generated based upon the integration data. Responsive to the number of detection events being between the first detection event count threshold and the second detection event count threshold, a blended output may be generated based upon the photon counting data and the integration data.

  • Patent number: 9579075
    Abstract: Among other things, one or more techniques and/or systems are described for measuring the attenuation of a line integral through an object via a photon counting cell (302) and via an energy integrating cell (304). That is, an imaging apparatus is provided that comprises a radiation source (208) and a detector array (210). The detector array is comprised of both photon counting cells (302) and energy integrating cells (304) arranged such that, during an examination of the object, attenuation of a line integral through the object is measured by at least one photon counting cell and at least one energy integrating cell. In this way, at least two substantially complete views of an object may be acquired, one from measurements yielded from the photon counting cell (and other photon counting cells) and one from measurements yielded from the energy integrating cell (and other energy integrating cells).

  • Patent number: 7573408
    Abstract: A system is described for correcting a switched input A/D converter circuit that performs a plurality of A/D conversions. The system includes an oversampling circuit, a switched input controller, separation circuitry, and a signal processing subsystem. The oversampling circuit is configured to convert one or more input analog signals into oversampled output signals. The switched input controller is configured to switch a separate calibration signal into the oversampling circuit, as a replacement for the input analog signal, for at least some of the A/D conversions. The separation circuitry is configured to separate the oversampled output signal from the calibration signal. The signal processing subsystem is configured to synchronously and separately process the oversampled output signal and the calibration signal so as to substantially reduce unwanted correlated response of the switched input A/D converter circuit.

  • Patent number: 5432339
    Abstract: A system and method of measuring geometric, positional and kinematic parameters of a rotating device is described. The system includes a plurality of spaced interval markings distributed about the periphery of a rotatable device, such as a disk, around a circle of known radius concentric with a geometrical center of the disk. At least three and preferably four sensors for detecting the markings are positioned to sense the markings as they rotate with the rotatable device. The sensors are angularly spaced relative to one another around the disk. Means are also provided for interpolating locations between selected markers by measuring the time since each sensor senses a marker. A reference marker is provided so as to establish a reference point of the rotatable device relative to a fixed point relative to the sensors.
